Chapter 15, Problem 3CP
Summary Introduction
To review:
The reason as to why the sympathetic division of the autonomic nervous system (ANS) is called the thoracolumbar division even when it extends to the sacral region from the cervical region.
Introduction:
Each and every division of the ANS is composed of two motor neurons. The first motor neuron has the cell body in the spinal cord or the brain and is called preganglionic neuron. The axon of this neuron exits the central nervous system (CNS) and extends to the autonomic ganglion. The second neuron is known as postganglionic neuron that synapses with the preganglionic neuron and extends till the visceral effector.

Why is the sympathetic division called the thoracolumbardivision even though its ganglia extend from the cervical regionto the sacral region?
Explain why the sympathetic division is also called thethoracolumbar division even though its paravertebral ganglia extend all the way from the cervical to the sacral region.
Why does the sympathetic division produce simultaneous effects throughout the body, in contrast to parasympathetic effects, which typically are localized to specific organs?

Pair each of these structures with their function listed below: -This limbic area is active when you are trying to memorize the names of brain areas. It is also severely atrophied in people suffering from late stages of Alzheimer’s Disease. -This limbic area is active when you are watching something that makes you feel sad. -This limbic area is active when you feel thirsty. -When the activity of this limbic area is increased you feel a sense of pleasure. -When this limbic area is damaged it often results in patients experiencing anterograde amnesia. -Damage to this limbic structure while rare often results in patients going into a coma. -This cortical limbic structure plays a large role in motivation and movement and has recently been…arrow_forward
